This is explained by using the basic theory of crystal chemistry and solid chemistry.

对此，用晶体化学和固体化学的基本理论进行了解释。

Flotation crystal chemistry principles and solution chemistry or physical chemistry principles of silicate minerals are emphatically discussed.

着重论述了硅酸盐矿物浮选的晶体化学原理和硅酸盐矿物浮选的溶液化学和物理化学原理。

Therefore, study on apatite crystal chemistry and mineralogical spectroscopy has both scientific significance and application values.

因此, 对磷灰石晶体化学、矿物谱学特征的深入研究既具有深远的科学意义,又有着很大的应用价值.
